The development of human cloning technology will have the greatest impact on.
Cloning is not nightmarish and inhumane as it is made out .
to be in science fiction movies. If we continue carefully researching cloning, mice and sheep .
will not be our greatest achievement. .
There are three different types of cloning: embryo cloning, adult DNA cloning and .
therapeutic cloning. Each type has a different purpose, procedure and outcome.
Embryo cloning is cloning that produces identical twins or triplets. One or more cells .
are removed from a fertilized embryo and are encouraged to develop into one or more .
duplicate embryos. The twins or triplets that are formed have identical DNA. This is a.
process that has been thought-out for many years. .
Adult DNA cloning, also known as cell nuclear replacement, is a procedure that .
duplicates an already existing individual. DNA from an embryo is removed and replaced with .
DNA from an adult. The embryo is implanted in a womb and allowed to develop. This.
process has not yet been tried on humans but has the possibility of producing a time delayed .
twin. Every cell in the body contains in its DNA all genetic material needed to create an exact.
clone of the body. Cells have been naturally programmed to perform limited functions, other.
functions have been turned off. Scientists believe such cells could be reprogrammed to behave.
as a fertilized egg.
Therapeutic cloning starts off like adult DNA cloning. Stem cells are removed from an .
embryo with the intent of producing tissue or a whole organ. The goal would be to produce a .
healthy copy of a sick person's tissue or organ to then be transplanted back into the person .
that supplied the DNA. This process would be superior to organ transplants from donors. The .
supply would be unlimited and there would be no waiting lists.
Cloning dates back to the nineteen seventies when frogs and toads were experimented .
on. The first gene was cloned in nineteen seventy-two.
